1 / 6 page TS2950-51 series 1-6 2003/12 rev. B TS2950/TS2951 series 150mA Ultra Low Dropout Positive Voltage Regulator Input Voltage Range up to 30V Output Current up to 150mA Low Drop Out Voltage 0.4V General Description The TS2950/A & TS951/A are low power voltage regulators. These devices are excellent choice for use in battery-powered applications such as cordless telephone, radio control systems, and portable computers. The TS2950/A & TS2951/A is features very low quiescent current (75uA Typ.) and very low drop output voltage (Typ. 40uV at light load and 380 mV at 100 mA). This includes a tight initial tolerance of 0.5% typ.(A version), extremely good load and line regulation 0.05% typ. and very low output temperature coefficient, making the TS2950/A & TS2951/A useful as a low-power voltage reference. TS2951/A have other key additional feature of unregulated input voltage transient of -20V below ground (reverse battery). The error flag output feature is used as power-on reset for warn of a low output voltage, due to following batteries on input. The logic-compatible shutdown input which enable the regulator to be switched on/off. The regulator output voltage may be pin-strapped for a 5.0, 3.3 & 3V of programmed from 1.24V to 29V with external pair of resistors. Using of as design, processing and testing techniques make TS2950/A & TS951/A superior over similar products. The TS2950/A is offered in 3-pin TO-92 package, The TS2951/A is available in 8-pin plastic SOP-8 package. Application Battery powered systems Portable instrumentation Avionics Automotive Electronics SMPS Post-Regulator Voltage Reference Portable/Palm top / Notebook computers Portable consumer equipment Radio control system Features Output voltage available in 5V, 3.3V & 3V Extremely low quiescent current Low dropout voltage Extremely tight load and line regulation Very low temperature coefficient Need only 1uF for stability Unregulated DC input can withstand -20V reverse battery and +60V positive transients Use as Regulator or Reference Stable with low-ESR output capacitors Current and thermal limiting Direct replacement for LP2950 & LP2951 sockets TS2951 VERSIONS ONLY Error Flag warns of output dropout Logic-Controlled electronic shutdown Additional voltage tap Output voltage sense Output programmable from 1.24 to 29V Ordering Information Note: Where xx denotes voltage option, available are 5.0V, 3.3V and 3V.
